Just as lipstick contains fish scales, and bird droppings are in spa facials, cosmetics manufacturers are now including snail slime as the latest oddity ingredients.

Making its way from Korea, topical snail gel is forecast to be the newest fad in skin care, says Cindy Kim and Alicia Yoon, co-founders of peachandlily.com, an e-commerce site providing snail gel products to U.S. consumers.

“Snail gel began with the ancient Greeks and was later rediscovered by Chilean farmers who noticed their hands were softer after touching snail secretion,” Yoon says. “Scientists have done a great job discovering the benefits of the filtrate and it has been trending in Korea over the last five to seven years.”

Now that it’s crossing over, U.S. consumers are wondering how the bizarre ingredient makes its way from slithering insects to skin care products. To grab the goop, scientists collect what lab-bred snails leave behind and process it into a powdery substance. This substance is what goes into the manufactured skin care products.

“No snails are hurt in the process,” Kim says.

But as peculiar as it sounds, the benefits of snail gel may outweigh the cringe-factor.

“When people hear ‘snail cream,’ they automatically become grossed out,” Kim says. “But once they open up the jar they smell it, feel it, and discover it’s lightweight and completely different than they thought.”

The extract is also billed as having positive effects on acne scarring, acne prevention, dryness and hyperpigmentation. Daily application of topical products containing snail secretion is also shown to significantly reduce fine lines and wrinkles, according to a 2013 study published in the Journal of Drugs and Dermatology.

Researchers gathered 25 participants experiencing moderate to severe facial photodamage. One side of the subjects’ faces were treated with snail secretion, while the other side was treated with a placebo for a 12-week period.

“A significant reduction was noted in fine lines, deep wrinkles, as well as elasticity,” the study concluded. “Dryness and roughness resolved in all patients by day 90 as well.”

Kim cites her customers as evidence of the secretion's effectiveness.

“We’ve gotten a lot of testimonials from customers that have had issues with acne and wrinkles and have seen improvements in their skin’s appearance since using snail gel products,” she says. “It’s been one of our best sellers on the site.”
